🔍 Key Concepts

• Engine-room terminology for gas turbines and jet engines used in marine propulsion • Difference between a primary fuel metering unit and downstream fuel distribution (like manifolds) • How manufacturers label the main fuel regulating component in technical manuals

💭 Think About

• Which option sounds like the device that actually measures and regulates fuel flow to match power demand and operating conditions? • In propulsion systems, is the key control usually named after the function it performs (controlling fuel) or the place it sends fuel (like a manifold)? • Which of these terms would you most likely see on a gas turbine fuel system schematic as the central control element?

✅ Before You Answer

• Identify which choice best matches a central fuel metering/controlling unit rather than a location or pipework • Eliminate any option that sounds more like a conference, organization, or event than engine hardware • Consider which term appears in manufacturer manuals for marine gas turbine or jet engine fuel systems as the main control unit
